The CORRECTION FACTOR can be converted into a SERIES OF MATHEMATICAL TERMS… In theory

it is required to use an infinite number of terms of such MATH SERIE, to obtain great precision. But for ratio (V/c) that is much smaller than ONE, the series is quickly convergent, thus it is not necessary to use large number of terms of the mathematical series.

= Classic Newtonian Physic Forces + Inertial Gravitational Forces (from second type of gravitational field (in fact such two forces can be added or subtracted in a straight line or can be found as a result of vector
